Example:

ConfT1mean(0.461368, 0.2776, 50, 0.95, "")

ConfT2mean The two-sample Student’s T confidence interval for the difference of two means.

ConfT2mean( x1, x2, s1,s2,n1, n2,C,pooled, [”configuration”])

Configuration: a string that controls what results are shown and the order in which they appear. An empty string "" displays the default: all results, including headers. The options in the configuration string are separated by spaces.

h: header cells will be created

DF: the degrees of freedom

T: the critical T-value

tXl: the lower bound of the confidence interval

tXh: the upper bound of the confidence interval

tXm: the midpoint of the confidence interval

std: the standard deviation

Example:

ConfT2mean(0.461368, 0.522851, 0.2776, 0.2943, 50, 50, 0, 0.95, "")
